Title: Signal supervision or correction apparatus
IPC: G05D1/00
Filed: 1977-07-05
Abstract: 1532383 Voltage measuring BBC BROWN BOVERI & CO Ltd 5 July 1977 [7 July 1976] 28149/77 Heading G1U A voltage equal to the average of a plurality of input voltages is produced, delayed and compared individually with each input voltage. Any difference larger than a pre-set amount causes the corresponding input voltage to be disconnected. The system described is a redundancy system in which ideally the input voltages would be identical. Excessive differences indicate faults and the arrangement described prevents the average signal changing excessively when a fault does occur.

Title: Welding methods and apparatus
IPC: B23K13/02
Filed: 1970-06-10
Abstract: 1314705 Welding by pressure AMF Inc 10 June 1970 [27 June 1969] 28180/70 Heading B3R A method of welding an edge surface of a first member to a second member, the cross-sectional thickness of at least the first member being enlarged at the edge to be welded, comprises feeding the two members so that the two surfaces which are to be welded together move in closely spaced parallel planes towards the weld point, heating the two members prior to the weld point by means of high-frequency current and applying upsetting pressure to the protruding metal at the edge so that metal is forced into the gap between the members to form a butt weld. The method may be applied to the welding at their edges 103, 104 of two generally flat members 109, 111 (Fig. 1); to the seam welding of thick-walled large diameter tubes 130 (Fig. 8); to the welding of L-shaped structural members (Fig. 21); to the welding of T-sectioned structural members (Fig. 19); or to the welding of fin elements to tubes (Fig. 10, not shown). In the case of welding a T-section member, Fig. 19, the member 14<SP>1</SP> to be welded by its edge is fed in a curved path in order to allow the welding current feed conductor 60 to be placed in proximity to the desired flow path for the heating current in the member 10<SP>1</SP>. The flow path for the current is necessarily longer in the member 14<SP>1</SP> than in the member 10<SP>1</SP>. The gap between the members is generally the minimum possible consistent with preventing arcing between the surfaces.

Abstract: 738,549. Door-operating apparatus. TRICO PRODUCTS CORPORATION. Oct. 16, 1953 [Oct. 17, 1952], No. 28636/53. Class 65(1). [Also in Group X] Power mechanism for operating doors and windows, and particularly for operating windows of vehicles, includes a power driven actuator 16 adapted to operate a vertically movable window carrier 8 for a window 3 slidable in guide channels 2 in the side door of a vehicle, a motion multiplying transmission being interposed between the actuator 16 and the window carrier 8. A cross arm 7, coupled to brackets 4 connected to the lower rail of the frame for the window 3, is secured to the carrier 8 which is slidably mounted on a stanchion 10 of C section, vertically spaced studs 14 on the carrier 8 carrying rollers 15 which engage within the stanchion 10, the latter being rockably mounted by a bolt 11 upon a plate 12 secured within the window receiving well. The actuator 16, mounted on a bracket 26 clamped to the plate 12, can be powered electrically, hydraulically, or by one, or two pneumatic piston and cylinder units 24, 23. As shown, two such units, controlled by a valve 37, are operated from the intake manifold 18 of the internal combustion engine, with, or without the aid of an auxiliary electric rotary pump 19 controlled by a suction responsive switch 22. Piston rods 25 are connected to opposite ends of the actuator 16 which has a path of movement substantially parallel to that of the window carrier 8. The motion multiplying transmission means comprises lifting and lowering cables 28, 29 looped under and over respectively each in a separate groove 34, partly round a pulley 33 mounted on the actuator 16, each cable having one end anchored by a head 30 to the respective end of the carrier 16 and the other end anchored to a fixed part, e.g. the adjacent end of the stanchion 10. The arrangement is such that when the actuator 16 is driven upwardly the pulley 33 lifts the cable loop 28 taking up cable from its carrier end and thereby lifting the carrier twice the distance covered by the actuator, reverse movement of which exerts a downward pull on the cable loop 29 to lower the window rapidly. A coiled spring 35 is inserted in the cable 29 to maintain the cables taut, a link, not shown, serving to limit the stretch of the spring. A counterbalance spring 40 actuating through links 41, 42, having their outer ends pivoted at 161 and 43<SP>1</SP> respectively to the actuator 16 and to a fixed part on the motor offsets the weight of the window upon the motor.

Title: Improvements relating to the catalytic cracking of petroleum hydrocarbons
IPC: C10G69/04
Filed: 1948-11-09
Abstract: Petroleum hydrocarbons are desulphurized by passing them in vapour form in admixture with hydrogen over a catalyst which combines activity for dehydrogenation of naphthenes to aromatics with activity for the conversion of organically combined sulphur to hydrogen sulphide, at a temperature and pressure such that the dehydrogenation of naphthenes contained in the fraction is effected to an extent not substantially in excess of that required to produce sufficient hydrogen to convert the organically combined sulphur as the fraction into hydrogen sulphide and to maintain the vapour phase in the reaction zone, a hydrogen-rich gas mixture being separated from the treated fraction and recycled to the desulphurization zone The desulphurized fraction is then passed to a catalytic cracking zone. As catalysts there may be used metal sulphides and oxides, especially those of the sixth group, for example chromium oxide, tungsten sulphide, nickel sulphide and cobalt molybdate or thiomolybdate, and the catalyst may be deposited on a carrier such as natural or heat-treated bauxite, activated alumina or kieselguhr.  The preferred catalyst is cobalt molybdate supported on alumina.  The desulphurizing reaction is preferably carried out at a temperature of 650 DEG -800 DEG F and at a pressure of 25-500 lbs./sq. in. Specifications 654,152, 663,038, 669,536, 669,552 and 679,175 are referred to.

Title: Manufacture of waterproof fibrous products
IPC: D21H23/00
Filed: 1929-09-26
Abstract: 319,745. Clapp, A. L. Sept. 27, 1928, [Convention date]. Moulding pulp.-A process for making waterproof fibrous products containing waterproof thermoplastic material such as paraffin consists in mixing such material with fibrous pulp suspension at a temperature above the melting point of the thermoplastic material, and forming the product from the suspension in hot condition. In addition, sizing material such as rosin size may be added to the pulp, and a precipitant such as alum then added. The process may be used for the production of articles such as bottles and containers in which the pulp is introduced into porous moulds and forced against the latter by air pressure. The pulp used may be ground-wood pulp, kraft pulp or sulphite pulp, and the thermoplastic material may be paraffin, montan wax, carnauba wax, rosin or asphalt. In an example, a. mixture of blank news or ground-wood pulp and kraft pulp is introduced into a beater, with sufficient water to permit proper disintegration. The water may be hot, or steam may be injected during heating, so that. the temperature is raised to 150 to 190‹ F. During the beating paraffin, or paraffin and rosin, at 150‹ F. is poured slowly into the stock. After being beaten for about two or three hours, the stock may be sheeted or may be introduced into moulds in hot condition, and heated air under pressure allowed to enter the moulds and force the pulp against the wire-screen faces of the moulds.
